Liverpool fell behind to Wolves when Milner was caught in possession near the halfway line and Raul Jimenez raced away to sweep a finish past Simon Mignolet.

Divock Origi’s thump brought the Reds level six minutes into the second half, but Ruben Neves thrashed in what proved to be the winner moments later.

“When you’re a team like us, with the players we have, you want to win every single game,” said Milner.

“We’re disappointed to not win and go through. We want to progress in every game we play.

“There were changes but we all train together all the time. I think we just didn’t get going really, didn’t get the passing going, just weren’t quite at our level.

“It was always going to be a tough game; they’re a good team, well organised. It’s not an easy place to come, we knew that from the game a few weeks back.

“I should have done better. The pitch all night was a bit tricky and balls were a bit lively, but it’s the same for both teams.

“It wasn’t as easy to get the passing going in those tight areas as we would have liked, but it was my mistake for the first goal and it cost us ultimately. Without that maybe it’s 1-1 and we get a replay.”

Jürgen Klopp made nine changes to his starting XI at Molineux, with Rafael Camacho and Curtis Jones handed senior debuts.

An early injury to Dejan Lovren then enforced another switch – meaning a first appearance for defender Ki-Jana Hoever 11 days before his 17th birthday.

And Milner, who captained the team on the night, praised the recruit from Ajax for the way he handled the occasion amid difficult circumstances.

“On the plus side, I think it’s good for the young boys to come in and get that experience,” the midfielder added.

“It’s not good to taste defeat but you normally learn more in a defeat than you do in a win.

“Ki coming on and playing like he did was absolutely outstanding. He’s going to be a top, top player – you can see that straight away. His temperament, he’s comfortable on the ball.

“Rafa and Curtis as well, it was tough because it wasn’t the easiest game to get on the ball and get the passing going and get Curtis into the game as much with his dribbling, but you get those games, especially in the FA Cup.”
